Hopefully this change should mean we can run some of the 'gc' test suite? See unimplemented in test/update-spec-tests.py

There are still a few issues that are being worked on, mainly on type checking regarding reference types. Because the two proposals are very different in their citations.

In addition, when submitting pr, I found an issue that has been raised about the coding of ref. In the gc proposal, the ref coding has changed, I hope to deal with it.

Hey - really excited for this change (just ran into the lack of gc instructions in the wat conversion tool). Is this still actively being worked on? Anything I could help with, e.g. looking into the ref handling and/or failing builds..?

I am confused by the first sentance of this PR, in wat2wasm v1.0.36 I get an error just trying to use struct.new.
Am I miss-understanding the wat syntax? Or is something else going on?

(module
  (type $TypeA (struct(field i32)))
  (func (export "main")
    (struct.new $TypeA (i32.const 42))
    (drop)
  )
)

>wat2wasm gc.wat -o gc.wasm --enable-all
gc.wat:6:4: error: unexpected token "struct.new", expected an instr.
                (struct.new $TypeA 42)
   ^^^^^^^^^^
